Recent advances in the internally heat-integrated distillation columns (HIDiC)
Distillation is the most widely used but the most energy-consuming separation process in the chemical industry. The internally Heat-Integrated Distillation Columns (HIDiC) are one of the promising alternatives of the conventional distillation processes to reduce the energy consumptions in chemical processes. The HIDiC has a similar structure to a heat exchanger. The rectifying section is contac...
متن کاملA thermo-hydraulic approach to conceptual design of an internally heat-integrated distillation column (i-HIDiC)
This paper presents a new approach to the conceptual design of internally heatintegrated distillation columns (i-HIDiC), based on column temperature profiles analysis. The paper proposes tools to assess the thermal feasibility of i-HIDiC designs and to determine whether the design and operation are feasible from the hydraulics’ point of view.
متن کاملIDENTIFYING OPTIMAL MIXTURE PROPERTIES FOR HIDiC APPLICATION
Internally heat-integrated distillation columns (HIDiC) are a new design option to provide a sustainable separation system. Although significant energy savings can be achieved using this setup, a considerable increase in investment cost penalizes the application. One major cost driver is the compressor cost, which depends on the relative volatility of the mixture to be separated. While mixtures...
متن کاملHeat and Mass Transfer Characteristics of an Annular Sieve Tray
An internally heat integrated distillation column, HIDiC, offers the maximum energy saving potential for difficult and energy intensive separations, such as propylenepropane and the like, which are carried out in tray columns. A novel type of HIDiC was developed by TUDelft, namely a concentric distillation column in which a low pressure annular stripping section is configured around a high pres...
متن کاملBasic design of a double-pipe unit type internally heat integrated distillation column (HIDiC)
Distillation is not only the most energy consumer but also the most frequently-adopted separation operation in chemical industries since it separates a mixture only by the difference among vapor pressures (boiling points) of components. So distillation is often called as the king of separation processes. Therefore, research and development of technologies on energy savings of distillation is an...
